Helen Page Echols, wife of a DuPont executive, commissioned American architect William Lawrence Bottomley to build this manor located near Wilmington, Delaware, in 1936. Nearly 30 years later, Henry E.I. du Pont (son of William du Pont, Jr.) bought the 61-acre property, known as Stockton-Montmorency, where members of his family still reside and raise Morgan horses.

An impressive cobblestone courtyard with a portico leads to the Colonial Revival–style home. Inside, a grand staircase ascends to a balcony landing overlooking the entrance hall, which features arched doorways, raised-panel wainscoting, original Gracie wallpaper, and double doors into the living and dining rooms. In addition to the second-floor bedrooms with en suite baths, there is a private guest suite with two sunny bedrooms and a shared marble-clad bath.

Outbuildings on the property include a two-bedroom farmhouse, three-bedroom tenant house, and 24-stall barn.
